Title: Improvements in and relating to the production of artificial silk
IPC: D01D5/14
Filed: 1937-03-04
Abstract: <PICT:0470622/IV/1> In the production of artificial filaments from cuprammonium cellulose solutions by stretch spinning methods wherein the extruded filaments and the coagulating liquid pass down a funnel device, eddying of the coagulating liquid is avoided or minimized when producing filaments of a total litre of less than 60 deniers by using a funnel with an upper opening not exceeding 40 m.m. in diameter.  Preferably, the upper opening of the funnel does not exceed a value of 5\std in millimetres, d being the total titre in deniers.  For a total titre of 10 deniers, the diameter of the upper opening of the funnel is preferably 16 m.m.  Preferably, the spinning funnels used differ only slightly from the tubular form and flare very little in an upward direction.  The outer cylindrical vessel, surrounding the funnel or the upper rim of the funnel, through which coagulating liquid is caused to flow from below to the upper rim of the funnel should be made as small as possible so as to leave only a narrow annular gap for passage of the liquid.  As shown, coagulating liquid flows from opening 1 in the outer vessel 2, up through the narrow annular gap 3, past the spinning nozzle 4, downwards through the narrow upper rim 5 of the funnel 6, and leaves the funnel through the lower opening 7 together with the artificial filaments.

Abstract: 1,270,222. Space dyeing. FARBWERKE HOECHST A.G. 12 Feb., 1970 [12 Feb., 1969], No. 6859/70. Heading D1L. Spaced dyeing of polyester or polyamide fibres is effected by injecting a disperse dyestuff and/or an organic pigment dyestuff dissolved or dispersed in an organic solvent into the fibres whilst wound on a bobbin supported on heated transporting equipment at a temperature of between 160C and 230C. The dye is subsequently fixed by allowing the bobbin to remain at this temperature for between 15 and 180 seconds. The transporting means may be a conveyor belt 4 provided with bobbin supports 3 which passes through a heated chamber 5 (heated by, e.g. infra-red heaters, high frequency driers or hot air or steam) the conveyor belt being halted each time a bobbin 2 is at the injecting means 1, so that the injection of the dye under pressure can be performed at one or more parts of the wound package. Each injecting mechanism includes a hollow injection needle with a perforated shaft for the injection of the hot dye under pressure, the length of which approximately corresponds to the thickness of the winding, it being such that it can penetrate to any desired depth in the winding. The intermittent halting of the conveyor belt is by, e.g. a mechanical or optical contact operative to stop the motor driving the belt, the restarting being by a mechanical contact. Different coloured dyes may be used, and injected simultaneously or at separate locations. Solvents for the dyestuffs may be an oxalkylation product of an aliphatic, aromatic, alkylated aromatic or cycloaliphatic compound, or a polyglycol ether.

Abstract: 709,109. Nozzles. BASTIAN-BLESSING CO. March 22, 1951, No. 6880/51. Class 69 (3) A draft arm nozzle for dispensing a liquid containing carbon dioxide includes a passage 13 in communication with a passage 14 in a rotatable valve member 15, the latter being rotated into either of two positions by a handle 16. In one position the liquid passes through a passage 20 and a passage 43, Fig. 2, in a stem 26 to the nozzle outlet. In the other position the liquid passes from a passage 18 to an annular chamber 22 and then through ducts 40 to a frusto-conical passage 41 between members 27 and 28. The latter are held in position by a nut 33 on the stem, and the liquid on leaving this passage strikes and passes down the frusto-conical inner wall of a collector 30. The said inner wall is at an angle of between 57 degrees and 87 degrees with the passage 41 and causes a braking of the liquid stream and prevents loss of carbon dioxide gas. In a further embodiment a spring is interposed between the nut 33 and member 27, and the passage 41 is formed by liquid pressure which forces the members 27 and 28 apart.

Abstract: 557,190. Protective cut-out arrangements; electromagnetic switches; resistances BRITISH THOMSON-HOUSTON CO., Ltd. May 27, 1942, No. 7193. Convention date, May 27, 1941. [Class 38 (v)] An overload protective system having instantaneous and inverse time-limit characteristics, and suitable for the protection of a motor 45, comprises a relay winding 26 energized in series with a mass 35 of negative temperaturecoefficient resistance material adapted to be heated conductively by short-circuited secondary windings of a primary winding 16 carrying the load. The mass 35 is preferably of the composition set out in Specification 540,344, [Group XXXVI], and is positioned between the rectangular-sectioned and channel-sectioned copper annuli 17, 18, respectively, to which the circuitleads are also connected, the winding 26 being energized either from the supply 37, 38 at constant voltage or from a variable-voltage extra secondary 19 to primary 16. The circuit may also include a remote milliammeter 39 calibrated directly in temperature units, and a further winding 26a of few turns in series with the load may constitute the instantaneous relayelement. With sustained moderate overloads, the higher induced currents in annuli 17, 18 heat the mass 35 and lower its resistance at a rate depending on the current and also, when energized by winding 19, upon the voltage of that winding; but if the supply is from a constant source the calibration of meter 39 is more uniform and the inverse-time characteristic more pronounced. The effect of 26a is negligible except at sudden high overloads, when it acts at once, but if this winding is omitted the winding 26 alone, when sufficiently energized by winding 19, provides instantaneous operation. The two windings 26. 26a, together with an anti-chatter shading ring 27, are assembled on a core 20 which preferably comprises a lateral extension 12 of the threelimbed transformer core. The armature 25 pivots in the adjacent side limb of the latter, and when attracted, de-energizes at contacts 28, 29 the circuit of holding coil 48 of the main contactor.
